How do we know that Christ's gospel is true?

The truth of Christ's gospel is rooted in the fact that it was made by Him and not by human effort. In the sermon, it is emphasized that the gospel is a divine creation that encompasses all aspects of Christ’s work—His incarnation, death, resurrection, and ascension. The preacher assures that the words of the gospel are pure and perfect, representing the very nature of Christ as the truth. Since the gospel comes from Christ Himself, it has been validated by His authority and His ongoing work, assuring believers that it is reliable and unchanging through all generations.
